If you are installing fewer than three modules, remove theblanking plate closest to the power supply first and the center blankingplate next.There are three blanking plates. Each covers two horizontal slots for serialconnectors. Unused slots require a blanking plate to maintain propercooling of the server and regulatory compliance.CAUTION: Powering on the server without a blanking plate or module ineach slot or without a cover can cause the server to overheat.
